| A non-equilibrium atmospheric pressure plasma incorporating an atomised surface treatment agent is generated by applying a radio frequency high voltage to at least one electrode positioned within a dielectric housing while causing a process gas to flow from the inlet of the housing past the electrode to the outlet. The voltage applied is sufficiently high to generate a non-equilibrium atmospheric pressure plasma extending from the electrode at least to the outlet of the housing. The electrode may be combined with an atomiser for the surface treatment agent within the housing. The electrode may comprise a radioactive material. The surface to be treated can be positioned adjacent to the plasma outlet so that the surface is in contact with the plasma, and moved relative to the plasma outlet. | ||||||
| 105 | Plasma Assisted Oxygen Decontaminant Generator and Sprayer | US12030962 | 2008-02-14 | US20080173621A1 | 2008-07-24 | Spencer P. Kuo |
| An atomic oxygen generator/sprayer is invented. An array of three magnetized torches running at 60 Hz is used to generate non-thermal plasma; thus, the plasma effluent has relatively low temperature (touchable) and yet contains high energy electrons (>5 eV) capable to dissociate oxygen molecules to atomic oxygen. The emission spectroscopy of the torch indicates that the plasma effluent carries an abundance of reactive atomic oxygen (RAO), which can effectively kill all kind microbes. A cap holding three pairs of rectangular permanent magnets is used to spread torches laterally into fan shape, which extends to a width exceeding 100 mm. The flux of RAO exceeds 2×106 cm−2 sec−1; its flow speed exceeds 20 m/s and it reaches out more than 20 mm. This invention is suitable for applications such as sterilizing carpets, clothes, and bed sheets. | ||||||

| 107 | Plasma brush apparatus and method | US11286019 | 2005-11-22 | US20070116891A1 | 2007-05-24 | Yixiang Duan; Qingsong Yu |
| An apparatus with a narrow slit chamber generates plasma having non-equilibrium characteristics and a brush-like shape at a temperature near room temperature and at a pressure of about one atmosphere. Plasma gas enters the narrow slit chamber. An external power source provides power to electrodes near the exit that excite the plasma gas and produce a plasma jet having a brush-like shape that exits the chamber. The apparatus operates with low power consumption, and the temperature of the plasma is low. Glow-to-arc transitions are prevented using a ballast resistor and appropriate plasma gases with the narrow slit chamber design. The brush-like shaped plasma extends beyond the exit of the chamber, and possesses the reactive features of low-pressure or non-equilibrium plasmas. The plasma brush apparatus can be used for plasma treatment, plasma cleaning, plasma deposition, plasma sterilization, and plasma decontamination of chemical and biological warfare agents. | ||||||

CONSTITUTION: An electrode(1) spraying plasma is used as an anode. Gas is inserted from the outside to a gas injection tube(5). The gas injection tube is used as a cathode. A porosity insulating material insulates the electrode and the gas injection tube between the electrode and the gas injection tube. The porosity insulating material has a plurality of through-holes passing through the inserted gas from the gas injection tube to the electrode. A protecting duct(4) insulates the gas injection tube from the outside. An insulation case(3) surrounds a part which is connected to the porosity insulating material among the electrode, the porosity insulating material, and the gas injection tube. The insulation case secludes the external diffusion of the discharge which generates the plasma between the electrode and the gas injection tube. | ||||||
